The Cop, the Professor and the President of the United States

The President says the arrests of a black Harvard professor by a white Cambridge policeman provided a "teachable moment" on race relations. We hear contrasting views of the "beer summit" at the Obama White House. Also, a military colonel says it's time to leave Iraq, and Ireland will accept two prisoners from Guantanamo Bay, but the Obama Administration is still investigating another, even though he's been there for almost seven years.
